Abstract

Lighting covers are disclosed. An example lighting fixture cover includes a sheet of material comprising a plurality of lenticules. A focal plane of the lenticules to be at a distance from a light source to enable light rays that travel from the light source through the lenticules to be directed in more than two directions.

Claims

1. A lighting fixture cover, comprising:

a sheet of material comprising a plurality of lenticules, a focal plane of the lenticules to be at a distance from a light source to enable light rays that travel from the light source through the lenticules to be directed in more than two directions.

2. The lighting fixture cover of claim 1, wherein the lenticules are embossed on to the sheet of material.

3. The lighting fixture cover of claim 1, wherein the lenticules comprise a lenticular pattern.

4. The lighting fixture cover of claim 3, wherein the lenticular pattern comprises between about 10 lines per inch and 200 lines per inch.

5. The lighting fixture cover of claim 3, wherein the lenticular pattern comprises approximately or greater than 50 lines per inch.

6. The lighting fixture cover of claim 3, wherein the lenticular pattern comprises between about 50 lines per inch and 90 lines per inch.

7. The lighting fixture cover of claim 1, wherein the lenticules comprise a viewing angle of between about 9 degrees and 55 degrees.

8. The lighting fixture cover of claim 1, wherein the lenticules comprise a viewing angle of between about 35 degrees and 55 degrees.

9. The lighting fixture cover of claim 1, wherein the lenticules comprise a arc angle of between about 50 degrees and 180 degrees.

10. The lighting fixture cover of claim 1, wherein the lenticules comprise an arc angle of approximately or greater than 110 degrees.

11. The lighting fixture cover of claim 3, wherein the lenticular pattern comprises an arc angle of approximately or greater than 50 degrees.

12. The lighting fixture cover of claim 3, wherein the lenticular pattern comprises a 3 dimensional lenticular pattern.

13. The lighting fixture cover of claim 1, wherein the lenticules are to be positioned in a direction substantially parallel to or perpendicular to the light source.

14. The lighting fixture cover of claim 1, wherein the lenticules comprise first lenticules positioned in a first direction and second lenticules positioned in a second direction different than the first direction.

15. The lighting fixture cover of claim 14, wherein the first lenticules are on a first side of the sheet and the second lenticules are on a second side of the sheet.

16. The lighting fixture cover of claim 1, further comprising a second sheet of material to be positioned adjacent or coupled to the sheet.

17. The lighting fixture cover of claim 16, wherein the second sheet comprises a plurality of lenticules.

18. The lighting fixture cover of claim 16, wherein the second sheet comprises a thickness greater than a thickness of the sheet.

19. The lighting fixture cover of claim 1, wherein the sheet comprises one or more of a filler or a pigment.

20. A lighting fixture cover, comprising:

a sheet of material comprising a pattern that enables light rays that travel from a light source through the pattern to be directed in more than two directions.

21. The lighting fixture cover of claim 20, wherein the pattern comprise a plurality of lenticules.

22. The lighting fixture cover of claim 21, wherein a focal plane of the lenticules is to be at a distance from the light source.
